What is an exponent?
An exponent indicates how many times the base is multiplied by itself. In 2³, 2 is the base and 3 is the exponent, meaning 2×2×2 = 8.
Applications
Exponents appear in population growth, compound interest, radioactivity, logarithmic scales (decibels, Richter), and computer powers (KB, MB, GB).
Scientific notation
Expresses very large or small numbers as a product of a coefficient (1-10) and power of 10. Facilitates calculations and comparisons in sciences.
